Description

  The present invention relates to a runner fixture that is attached to the upper part of a folding door, and more specifically, a hanging door type folding door in which a folding door is suspended by a traveling runner that is provided with rollers and is allowed to run in an upper rail, The present invention relates to a runner mounting tool for a folding door that can be used in common with a door-supporting type folding door that is supported and has a sliding pivot that is fitted to a groove portion of an upper rail at the door end side upper end and guides a slide.

  Conventionally, as a runner fitting attached to the upper part of a folding door, the following Patent Document 1 has an opening in a side surface for introducing the attachment portion from the horizontal direction in the attached portion, and this opening is formed in the vertical direction. Provided, the temporary holding portion connected to the rear side of the introducing portion, and the mounting portion provided between the temporary holding portion and the introducing portion to move horizontally and come out of the temporary holding portion. A retaining portion for preventing, and a main fixing portion that is connected to the lower side of the temporary holding portion and for fixing the mounting portion in the horizontal and vertical directions by relative movement of the mounting portion and the mounted portion in the vertical direction. What has been disclosed is disclosed.

  Furthermore, the following Patent Document 2 includes a suspension shaft attached to a runner body that travels on a rail, and a connecting member attached to a door plate, and the suspension shaft has a relatively large diameter portion and a relative diameter. And a small-diameter portion having a small diameter, and the connecting member is elastic and has two pieces arranged opposite to the axis of the suspension shaft so as to be narrowed downward. A locking piece that is locked to the flange portion is provided, and the suspension member and the connection member are attached and detached by moving the connection member in two directions, ie, the radial direction and the axial direction of the suspension shaft.

  However, in the runner attachment described in Patent Document 1, when the door is attached, the attached portion moves from the introduction portion of the attached portion toward the temporary holding portion by horizontally moving the attached portion toward the attaching portion. Since it is pushed in the horizontal direction and temporarily held, it is secured at the retaining part, and then the door is fully fixed by lifting the door. It was complicated.

  Further, the runner attachment described in Patent Document 2 also requires two procedures for moving in two directions, ie, the radial direction of the suspension shaft and the axial direction, and the suspension work is complicated. Further, the locking piece is formed in a long shape extending from the lower part of the fitting part to the lower part of the expanding part, and when locking with the suspension shaft, the flange part of the circular suspension shaft and Since the structure is such that two parallel long locking pieces are engaged, it is necessary to apply an extra pushing force to the extent that the flange portion expands the locking pieces when moving in the axial direction. There were problems such as poor workability. Furthermore, in order to release the engagement state, the engagement piece is expanded by pushing up a mountain-shaped unlocking body installed below the engagement piece. In order to expand, a large push-up force must be applied to the unlocking body, and there is a disadvantage that workability is poor in this respect.

  In view of such problems, the applicant of the following Patent Document 3 can complete the suspension substantially by the operation of horizontal movement, facilitate the suspension operation, maintain the reliable suspension state, and easily. We proposed a runner fitting for a sliding door that can be released from a suspended state. Specifically, a runner body that can run along the traveling rail, a connecting shaft that protrudes downward from the runner body, and a runner fixture that is fixed to the upper part of the suspension door and connected to the connecting shaft. And the connecting shaft is detachable from the runner fitting, wherein the connecting shaft includes a large-diameter portion having a relatively large diameter, and the runner fitting Are arranged to be opposed to each other on the left and right sides, and are rotatably supported around the vertical axis, and are rotated by inserting the connecting shaft from the horizontal direction so as to hold the large-diameter portion of the connecting shaft in a non-removable manner. There has been proposed a structure including a connecting shaft attaching / detaching mechanism including a locking member and an engaging block that engages with the locking member and allows the connecting shaft to be held and released.

Upper fixing bearing bracket 62 Therefore rotatably supporting, and also present Orito of Tomoto-supporting travel freely between the structure along the groove portion of the upper rail 60 sliding pivot 63 provided on the door leading end side upper portion.

  The runner fitting used for the former hanging door type folding door has a structure that is connected to the connecting shaft protruding from the lower surface of the traveling runner that runs in the upper rail, and is used for the latter door support type folding door. The runner attachment has a structure that supports the sliding pivot. Therefore, as a manufacturer, it is necessary to prepare both a runner mounting bracket suitable for the above-mentioned hanging door type folding door and a runner fitting suitable for the above-mentioned door-supporting type folding door in advance. In addition to being complicated, the production cost was also increased.

  Therefore, the main problem of the present invention is that the folding door is folded by a running runner that is provided with rollers and is allowed to run in the upper rail, and the upper rail is supported on the door side and on the upper end of the door. An object of the present invention is to provide a folding door runner attachment that can be used in common with a door-supporting type folding door that includes a sliding pivot that fits into a groove and guides a slide.

In order to solve the above-mentioned problem, as the present invention according to claim 1, a runner attachment that is attached to an upper side end of a folding door,
The runner fixture has an internal space that communicates with an opening formed on the front surface, and includes a case body that is embedded and fixed on a side surface of the folding door, and the case body includes a flat upper surface portion on the top. And a housing case in which a groove portion is formed so that the shaft member can be inserted from the horizontal direction on the upper surface portion.

Release the accommodation holding state. Then, simultaneously with the release of the housing and holding state, the release portion 31c is sandwiched between the protruding shafts 30 and 30 ((B) in the same figure). As a result, the space between the projecting shafts 30, 30 is expanded, and the projecting shafts 30, 30 ride on the inclined side portions 31 a, 31 a, so that the engagement block 22 is moved outward by the urging force of the spring member 23. When moved, the lock members 21 and 21 are rotated to release the holding state of the connecting shaft 7 so that the suspension door 2 can be removed (FIGS. (C) and (D)).
(Second embodiment)
The second embodiment is different from the first embodiment in the form of the lock member. Specifically, as shown in FIG. 12 and FIG. 13, a gear portion 28 a that protrudes in the lateral direction is formed on the lower surface of the main body portion of each lock member 28 so as to mesh with each other while being opposed to each other. ing. Accordingly, the lock members 28 and 28 can be rotated in conjunction with each other.

  A method for suspending the suspension door 2 when the lock members 28 are used will be described with reference to FIG. As shown in FIG. 5A, the runner attachment 8 portion holding the locking members 28 in the expanded position is moved in the horizontal direction toward the connecting shaft 7. Then, the large-diameter portion 7b and the shaft portion 7a of the connecting shaft 7 come into contact with the large arc portion 21d and the small arc portion 21c of the lock member 28, respectively, and the lock member 28 starts to rotate about the communication shaft 24 as a rotation center. At this time, even if the connecting shaft 7 comes into contact with only one lock member 28, the pair of left and right lock members 28, 28 rotate at the same rotation angle because the gear portions 28 a, 28 a mesh with each other. To move. Thereafter, the projecting shafts 30, 30 provided on the lock members 28, 28 are securely accommodated and held in the accommodation holding portion 31b so as to be immovable ((B) in the figure).

[Usage form of sliding pivot type]
